The commercial values as expressed in the last column 
of the above table vary greatly. It is probably seldom 
that horse manure from city livery stables is worth as 
much as $2 a ton for the actual supply of plant food. 
78. Horse manure. — The bulk of manures purchased in 
the cities is horse manure. It is much drier than most 
other manures, looser in texture and acts more quickly 
than cow manure. It is practically the only kind of ma-

in compost piles is very rapid and it must be carefully 
managed to prevent the loss of ammonia. 
79. Cow manure. — Cow manure is highly valued by 
vegetable growers as a slow-acting manure. It is much 
slower in decomposition than horse manure and may 
be safely applied nearer the time of planting. Limited 
quantities can often be bought at reasonable prices in 
small towns. 
80. Hog manure is also slow in action and generates 
very little heat in decomposing. It is valued by vege- 
table growers, although very small quantities are used. 
Some market gardeners near eastern cities have hogs 
fed mainly with the refuse from kitchens, and kept gen- 
erally in cellars or covered sheds that are frequently very
